CompTIA is one of the larger IT certifiers in the world. Over 2.5 million IT professionals have received certifications from CompTIA. According to Business News Daily’s survey, CompTIA’s Linux+ certification ranked among the top Linux-related certifications that employers were seeking.
Currently, CompTIA has five distinct categories of certifications:
- Data & Analytics
The Linux+ certification falls under the Infrastructure category (along with Cloud+ and Server+) and is perfect for early-career systems administrators who want to work with Linux systems.
Linux+ is a newer certification. CompTIA started offering it in April of 2019. It is designed as a junior-level certification for those starting out in an IT infrastructure career. Specifically, one would be working on Linux systems.
Who gets certified?
According to CompTIA, common jobs that benefit from the Linux+ certification are:
- System Administrators
- Linux Administrators
- Network Administrators
- Junior DevOps Support Engineers
- Linux Engineers
- Web Admins/Developers
Since Linux has been around since modern computing began, professionals with open source skills are highly sought after. The Linux Foundation reported that 69% of hiring managers are more interested in hiring someone with a certification vs. someone without.
CompTIA reported the average annual salary of a Linux+ certificate holder was $77,360. They also reported salaries for other job titles that commonly use a Linux+ certification from both the U.S. Bureau of Labor Statistics and Glassdoor. :
